Radical feminist theorists do not seek to make gender a bit more flexible, but to eliminate it. They are gender abolitionists, and understand gender to provide the framework and rationale for male dominance. In the radical feminist approach, masculinity is the behavior of the male ruling class and femininity is the behavior of the subordinate class of women. Thus gender can have no place in the egalitarian future that feminism aims to create.
